The bad blood between Theranos and The Wall Street Journal is now a game.

Employees at the struggling blood testing company created a video game in which players shoot at photos of WSJ reporter John Carreyrou, according to Business Insider, which published a video of the game on Thursday.

In a nine-second clip, photos of Carreyrou march across the screen in a manner similar to the old Space Invaders format. Players attempt to shoot the heads before they reach the bottom.

Carreyrou, who has written a book about the company, has been aware of the game for about a week. On Thursday, he tweeted that the game's creator sent him a copy. He just needed some cables to set it up.
